While flat roofs are aesthetically appealing and energy efficient, they often end up requiring more attention than other roofing types.
Water Accumulation
Pooling water is the main cause of flat roof deterioration. When the water that hits your roof accumulates, the membrane breaks down and causes leaks. This issue can be solved by adding a tapered insulation system that will shed the water off your roof.
Alligatoring
Constant exposure to the elements can result in a cracked membrane that resembles the skin of an alligator. To prevent this, our company uses a complete line of coating systems that can be applied to any type of roofing. The coats form a watertight seal over the entire roof, protecting its surface. This coating can extend the roof’s service life and help you save money in the long run.
Edge Damage
When water does not drain properly, it remains at the edge of the roof. This can be detrimental to your flat roof. The best solution is to ask for experts’ help. They have in-depth knowledge on how the system works, which translates to a job well done.
What Central Pennsylvania property owners should consider
Problem Areas of Commercial Flat Roofs is best understood in the context of the whole property, not from one symptom alone. The age of the materials, previous repairs, water-management details, installation methods, and nearby exterior components can all affect what is visible. Central Pennsylvania’s mix of heavy rain, wind, summer heat, falling leaves, freeze-thaw cycles, and winter weather can also make the same concern look different from one home or building to another.
Start with observations that can be made safely. Avoid climbing onto the roof or disturbing damaged materials. Instead, note when the concern appeared, whether it changes during particular weather, and whether it is isolated or occurring in several areas. Photographs taken from a safe location and notes about prior work can help a professional understand the history without relying on memory alone.
Details worth documenting
- leaks, staining, or ceiling changes and when they occur
- the age and known repair history of each roof section
- drains, scuppers, penetrations, seams, and rooftop equipment
- areas affected by foot traffic or recurring service work
- warranty records, prior inspection notes, and existing maintenance
These details do not replace an on-site evaluation, but they make the conversation more useful. They also help separate a maintenance item from a repair need or a larger project. A clear evaluation should explain the observed condition, the likely scope, the surrounding components that were checked, and any assumptions that could affect the recommendation.
Questions to ask before authorizing work
- Can work be phased around operations and occupant needs?
- What documentation will be provided for maintenance records?
- Which conditions should be monitored after the immediate work?
- Is the concern isolated or part of a broader system issue?
- What repair options preserve service life without masking damage?
- How will drainage and rooftop penetrations be evaluated?
Ask for the proposed work in writing and compare scopes rather than price alone. Materials, labor, disposal, cleanup, ventilation, flashing, permits, warranties, and possible concealed conditions should be easy to identify. If alternatives are available, the practical differences should be explained in plain language so the decision reflects the property’s needs and the owner’s priorities.
